[V8] Brake Line Bleeding - Revisited.

[Etdmail@cs.com]

 Hi All

 Congrats to those, who have added, to their Audi family.

 In the event, the ABS-Pump, won't bleed the system.

 In the past - I've used a 'spare' brake master-cylinder cap
 with the correct-sized hole cut, in it's center, to accept a
 tire/rim's valve-stem .. And then used a bicycle-pump to 
 supply the pressurization to master and lines.

 Of course, gravity, is cheaper still. ;-)

 Also have found the (Valvoline) Synthetic brake fluids available 
 in AutoZones, etc. .. Gives good service and leaves a slightly 
 harder brake-pedal, hot or cold.

 HTH
 Best,
 Ed

Someone made a simple brake bleeder out of a small garden type pump
sprayer, (about $10), a cheap pressure gauge ($10), and a length of hose
attached to a universal brake master cyl cap with a brass hose fitting
placed in the middle.  Pour in some brake fluid, pump up to 20-30 psi,
and bleed away.  I going to install some stainless lines soon and was
going to make one.  Will post my results.

The brake pressure accumulator (bomb) contains hydraulic oil from the power
steering/power brake pump, not brake fluid from the brake lines.  The
pressure from the hydraulics system goes to the booster behind the brake
master cylinder and provides assist in operating the master cylinder.  You
do not need to "bleed" the hydraulics.  The pump provides upwards of 2000
psi of pressure to the fluid and will self bleed through the hydraulics
reservoir.  

You should flush the brake lines through the brake master cylinder to each
of the caliper bleeder screws.  Audi calls for pressurized brake bleeding.
I use the Eezibleeder  <A HREF="http://www.rdent.com/images/eezibleed.jpg">
http://www.rdent.com/images/eezibleed.jpg</A>   There
are several reports in the archives of Audifans.com about making your own
pressure bleeder for under $15.  I hook my Eezibleeder up to the master
cylinder and run a pint of brake fluid to each caliper for my annual system
flushing.  The sequence is RR, LR, RF, LF.  The Eezibleeder container
only holds a pint, so I have to disengage it and refill for each corner.
I use an air pressure gauge/control device to keep the air pressure to my
Eezibleeder at about 15 psi.
